Description
The “trackless trolleys,” which are fueled by electricity, have been in operation for over 80 years and are a major component of King County’s zero-emission fleet. King County will explore opportunities to increase the use of the electric trolley bus system in alignment with plans to transition to a 100 percent zero-emission bus fleet. King County will complete and implement priority recommendations from the Trolley Optimization Planning study, including increasing utilization of trolley buses on weekends, and upgrade the trolley fleet with new batteries for longer off-wire capability by 2027. Capital investments identified by the Trolley Optimization Planning study and installation of the new batteries will allow for King County to reduce instances of dieselization of trolley routes, which in turn decreases GHG emissions.
